Answer / venkat

as the distance between two electrodes is large, 230v is
not sufficient to produce arc between two electrodes.high
voltage is required to produce arc. Igniter is used to
produce high voltage between two electrodes of the sodium
vapour.

Answer / hjit4u

Purpose of the ignitor is to give pulese to the choke to
start light the lamp.

Answer / ssreenu

In other words the purpose of Ignitor is just like a
starter in tube set.

Answer / raja

ballast used in sodium vapour lamp is a normal coil which is
used to boost high voltage ., igniter used to give pulse to
ballast to boost voltage at a short intervals

Answer / anil kumar guru

Due to differnce between two electrode is more in hpsv lamp hence high voltage is required at the Time of starting by changing current across the blast that do ignaitor

Answer / navneet

we can use ignitor only, use of capacitor is not necessary....

Answer / sidlingu

ignitor is a temperature controller

there is a power transformer 66/11kV in delta-delta connection has 5 feeder coming out from the secondary side. One of the feeder in it normally loaded (loaded than other feeder)and this feeder usually trips with double OCR causing the bank transformer to trip. Now if the load of this feeder is put on other transformer then that no problems occurs on that transformer or the load. However normally all the test(IR, PI, short ckt, open ckt,grounding test and other ) has been conducted for this but evertything transformer..... I am not geting what is the actual problem...
